Touch-ready 16-bit MCUs combine USB connectivity, low power and large memories
Microchip’s 16-bit PIC24FJ256GB1 MCU
family is ideal for USB-enabled userinterface
solutions, benefiting from 2.6µA
standby current, up to 256kbyte on-chip
Flash and 16kbyte RAM, a powerful USB
controller, and support for touch-sensor
integration.
The 12-member PIC24FJ256GB1 family integrates
USB 2.0 device, embedded-host, dual-role and On-The-Go
(OTG) functionality, allowing engineers to
take full advantage of the speed and ubiquity of
USB connectivity. Engineers can also use the onchip
Charge Time Measurement Unit (CTMU) in
conjunction with royalty-free touch-sensor software
to implement capacitive touch capabilities to
create advanced user-interface solutions.
In addition up to four UARTs, three SPI ports and
three I2C ports expand control capabilities, while
the devices’ Peripheral Pin Select pin-mapping
function increases I/O flexibility.
Package options include 64-pin, 80-pin,
or 100-pin Thin Quad-Flat-Pack (TQFP). The
PIC24FJ256GB1 family is also pin-, peripheral- and
software-compatible with Microchip 32-bit MCUs.
This permits efficiency-boosting design re-use, and
allows developers to quickly build cost-effective
end products spanning a broad performance
spectrum.
The supporting starter kit aids rapid time to
market by providing an integrated in-circuit
debugger and programmer, USB device and host
connectors, tri-colour LED, capacitive touch pad
and an OLED display. Menu-driven demonstration
software allows developers to quickly build datalogging,
thumb-drive, and graphics applications.
